Among the objects of this invention are the provision of an improved machine for gathering crops into windrows; the provision of means for separating dirt and stones from vegetation; the provision of means which will render it impossible to accidentally separate a crossconveyor from a pick-up unit; the provision of means to render more easily and readily the attachment and detach ment of a cross-conveyor unit; the provision of means for driving an apron of a pick-up and, simultaneously, driving the apron of a cross-conveyor; and such further objects, advantages, and capabilities as will hereafter appear and as are inherent in the construction disclosed herein.

Our invention further resides in the combination, construction, and arrangement of parts illustrated in the accompanying drawings and, while we have shown therein what is now regarded as the preferred embodiment of we desire the same to be understood as illustrative only and not to be interpreted in a limiting sense.

In the drawings annexed hereto and forming a part hereof,

Fig. 8 shows a fragmentary plan view of the rear part of the pick-up with a the plane indicated by the line 88 in Fig. 6;

Fig. 9 shows a cross-section of the structure shown in Figure 8, along the plane indicated by the line 9-9 in that figure; and

Fig. 10 shows a plan view of the left hand end of the structure shown in Fig. 7, Figs. 7 and 10 showing the right and left ends, respectively, of the structure shown in Fig. 5.

In the mobile pick-up unit P, best shown in Fig. l, the crops are picked up in the customary manner by pick-up mechanism in the form of a drum or cylinder 1 provided with protruding and withdrawable fingers 2, as is well known. These crops are delivered to a draper or apron 3- and carried upwardly and rearwardly to a cross-com 'veyor5, when such is used. This cross-conveyor is detachable and can be used or not as conditions require.

portion of the cross-conveyor, along bers and bar thus which is supported 2 When not used, a single windrow when used, it serves to unite the windrow with one or more previously laid, resulting in a multiple windrow.

In this vegetation handling machine, it is necessary to get the crop to the cross-conveyor and, therefore, the draper or apron 3 is placed above and to the rear of the pick-up drum 1 so that the crop will be elevated and dropped on the draper 4 of the cross conveyor 5, to be carried toward the right of Fig. 2. In this figure, a roller 6, at the end of the draper 4, is spaced from the end of the draper and is provided with ridges to form a species of slinger which carries the crop over past the roller 6 and forms a windrow. A space 8 (Figs. 8 and 9) is left between the roller 6 and a roller 9, forming a part of the cross-conveyor. This space 8 allows stones and dirt, picked up, to be dropped on the way to the roller 6, but the crop is not also dropped through this space but is delivered in a windrow at the end of the cross-conveyor.

This cross-conveyor unit has another roller 10 at the left end thereof, as shown in Fig. 4. This cross-conveyor has an upstanding rear frame in the form of a wind shield 11 to prevent vegetation from being thrown off the rear of the conveyor platform. Metal braces 12 and 13 are placed longitudinally of the shield, and a support 14 rises from these braces 12 and 13 and journals the rear part of a telescopic shaft assembly 15.

At one end of the shield 11 is a stiffening member 18 which serves to stay or support the shield. A rod or link l5 is connected to this stiffening member 18 and is also detachably connected to a bracket 20 rising from a transverse, upper horizontal member 33 forming a part of the main frame of the pick-up unit. A second stiffening member 22 also rises from the metal braces 12 and 13 and helps hold the shield 11 in place. A rod or link 23 is connected to the end of the stiffening member 22, the second end of the rod 23 being detachably connected to one end of a bracket 35 on the horizontal mem- Another rod 24 is of vegetation results;

unit 5. A horizontal shaft 21 has crank arms 29 extending therefrom, and from these crank arms 29 extend flexible means or chains 30 which are connected at their other ends to drum-supporting end plates 31 to vertically adjust the pick-up drum.

The horizontal shaft 21, as shown in Fig. 1, extends through sector 32, which is secured to the tubular frame member 33. Laterally spaced apart, generally upright frame members 34 are secured to and depend from the cross member 33 and are in turn rigidly cross-connected by a transverse lower main support or bar 33a the memaifording a pick-up unit main frame on and rises from ground wheels 47, which wheels are journaled on suitable bracket and axle assemblies 47a. A drive shaft 36 is connected to the the roller 6 to be driven. p The shaft 44 serves also as a transverse pivot for the end plates 31, between which the pick-up drum 1 is jo rnaled. .Hence the adjusting means afforded by the lever 28 operates throughthe rockshaft 2 1, arrns 2; 9 an d chains30'to adjust the height of the drum 1.

Plates or ears 48, welded to the pick-up unit lower frame member 35, are spaeed slightly apart andhave holes thereth' ongh lto receive a pivot member or rod ,49 ;to f orrn 'part 'of a hanger ,or hanging means for supporting the .crossweonveyorgunit whichhas a fronttransyerse frame 'r'nember 5a includin g hoolcsfitl to be hooked von ,the ,rod
